Answer:
C) There will be an increase in government purchases as the economy has more income.
Explanation:
The long run aggregate supply (LRAS) curve includes the output of an economy when all the factors of production are being used at full capacity. The position of the LRAS curve depends on the number of workers, the amount of capital, and the available technology.
Every time an economy (or even a company) experiences a significant technological progress, its productivity increases, increasing the total output.
